Usage

• How to run the algorithm proposed in this work?

$ roslaunch grf_swarm grf_swarm.launch # or grf_swarm_nav.launch to more informations

• We contrast our stochastic approach with a gradient-type showing that it easy get trapped into local minima.

• Approach proposed by Santos et al. 2020. This approach uses global knowlegde about the position of the robots and then we use as a baseline approach.
